Patented May 14, 1940 UNITED STATES PATENT OFFHIE Application July 6,1937, Serial No. 152,132 Renewed April 8, 1940 4 Claims.

This invention relates generally to improvements in fabricateddevicesand has particular reference to fabricated elements capable ofbeing applied to the walls of a building to bind and hold the plaster insaid structures.

The principal object of the invention is to provide a combined metallicfabricated material that may be produced in sections to be later appliedto the uprights of a building structure, that is, to the studding ofsaid structure to properly hold and bond the plaster finish to beapplied thereto in the final finishing of the Walls of the building.

Another object of the invention is to produce a fabricated material inthe form of lath that is cheap to manufacture, that combines rigidity,is pliable and that may be quickly and easily assembled in units to beapplied to the walls of a structure of any description.

A further object of the invention is to provide a fabricated section orsections of the character set forth that may be produced in largequantities and in a continuous operation.

Additional to the foregoing objects is that of providing a combinedmetallic and fabric lathing structure that embodies means for stiffeningthe structure of the material, means for waterproofing the same, andmeans for holding the plaster which may be later applied thereto.

Other objects and advantages of the invention will become apparent withreference to the accompanying drawing in which- Figure l is a plan viewgenerally illustrating the features of my invention; and

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure1.

It is apparent that various metal lath constructions have been producedin the art of building devices, but none of these combine the featuresincluded in the present structure, in that, to my knowledge, allso-called metal lathing of this type consists entirely of fabricatedmetal, while in the present device a combination of elements is producedto not only combine a metallic structural arrangement of elements but toalso include means for waterproofing the same as well.

The preferred form of my invention is shown in the drawing and includesa section of fabricated material 5 generally indicated in the figuresand which may be turned out in an elongated sheet and cut in the desiredsections.

This sheet of fabricated material is constituted of a corrugated basepaper of coarse character,

a waterproof lining 1 preferably of tin foil, metallic stiifeners 8 ofU-configuratio'n and a covering 9 of burlap of open mesh material, thewhole being wire stitched together by means of wire 5 stitching Hi.

In this manner a composite metallic and. fabric section is formed whichcombines metal stiffeners, a light corrugated body section, means forwaterproofing the same, and means for 10 stitching the sections togetheras a unit.

The transverse stififening ribs 8 are stitched to the structure asindicated by the stitching l l in Figure 1. 1

It will, therefore, be apparent that a plaster- 16 board backing hasbeen produced that is light in weight, may be easily cut to the desiredsize, and that may be quickly applied to the studding or uprights of anybuilding structure.

I claim and desire to secure by Letters Patent 20 of the United Statesthe following:

1. In a fabricated lathing of the class described, a non-metallic base,a waterproofing consisting of tin foil arranged against the base,stiffening elements positioned upon said base, a non-metallic elementarranged over the stiffening elements, the whole being wire stitchedtogether as a unit.

2. A section of fabricated material comprising lathing sections capableof being applied to a building structure to receive a plaster finish,said sections being constituted of a corrugated base,

a tin foil waterproofing section, netting arranged above the basesection, and wire stitching extending thru all sections that combine thesame in a unit.

3. A fabricated material for building structures providing a base forplaster finish in sheet form, said base consisting of metallic andnonmetallic elements in sheet form' superimposed 40 uponeachother, wirestitched together as units, and metallic stiffeners riveted upon thebody of the material tohold the same in position.

4. In a fabricated lathing of the class described, a non-metalliccorrugated base in sheet form, a waterproofing element also in sheetform arranged upon said base, stiffening elements in sheet form rivetedupon said base, and a netting element in sheet form superimposed andwire stitched to the stiflening elements and secured to said base. i i
